Title: Electromagnetic clutch
Inventor: UEHARA FUMIAKI
IPC: F16D27/07
Filed: 1990-10-12
Granted: 1995-08-01
Abstract: An electromagnetic clutch is disclosed which includes a clutch rotor having a first friction surface and an annular armature plate having a second friction surface. The first friction surface and the second friction surface face each other. A friction member is made of nonmagnetic material and is fixedly disposed within a second groove formed at the second friction surface of the annular armature plate. A first end surface of the friction member projects with respect to the second friction surface of the annular armature plate. The first friction surface of the clutch rotor is provided with a first annular groove to receive the projecting portion of the friction mem-ber. Therefore, the depth of the second groove becomes smaller. Consequently, a reduction of the number of magnetic lines of flux which radially penetrate through an annular portion of the annular armature plate at the location of the second groove is prevented. Thus, the magnetic attraction between the annular armature plate and the clutch rotor is increased without increasing the weight of the electromagnetic clutch.

Title: Signal detecting circuit for detecting a signal specified in a designated frequency
Inventor: SATO TOSHIYUKI
IPC: H03B19/16
Filed: 1991-03-19
Granted: 1995-01-10
Abstract: ABSTRACT            A designated burst signal specified in a designated frequency is detected from an all-inclusive signal specified in a number of different frequencies.  The frequency of the all-inclusive signal is first multiplied by a multiplying factor so as to produce a multiplied output signal.  Then a phase-lock loop operation is performed between the multiplied output signal and an oscillated signal produced for performing the phase-lock loop operation and specified in a multiplied frequency of the designated frequency by the multiplying factor.  This produces a phase-lock output signal and which is then compared with the multiplied out-put signal to produce a detected output signal representing whether the designated burst signal is in the all-inclusive signal.

Title: Method and apparatus for filtering blood in a blood vessel of a patient
Inventor: GUENTHER ROLF
IPC: A61B17/00
Filed: 1991-08-01
Granted: 1998-08-18
Abstract: A method of filtering blood in a blood vessel of a patient wherein a catheter is initially introduced into the blood vessel and then advanced to a desired location within the blood vessel.  Subsequently, a portion of a positioning means having a filter distally attached thereto is guided through the catheter.  The filter is then positioned at a location beyond the distal end of the catheter within the blood vessel with the positioning means.  The positioning means is then locked to the catheter.  The catheter is then anchored to an object located outside of the blood vessel.  Thereafter, an amount of blood is filtered within the blood vessel with the filter.  The filter can be readily repositioned by unlocking the positioning means from the catheter, repositioning the filter within the blood vessel with the positioning means and then relocking the positioning means to the catheter.

Title: Interprocessor switching network
Inventor: GRANT ELWYN E
IPC: H04L12/64
Filed: 1991-11-29
Granted: 1994-09-06
Abstract: A digital switching network for providing simultaneous connections  among  user  processors  of  processor-based communications  equipment.   The user processors act as originators  and  destinations  of  data  communications packets.    Packet  data  connections  are  through  node controllers, which communicate with gateways, which are connected to a switching network via packet links.  Control messages  are  communicated  between  node  controllers, gateways, and an interchange control subsystem via various control message links.  All control message processing and packet data transmissions are synchronized with a packet frame  synchronization  signal,   and  processing  tasks performed by each of the network subsystems are pipelined so that they occur simultaneously.  Service requests are queued  in a central  queue  in the  interchange control system.   The synchronization and queueing simplify the control messages that are required to set up and release the connections.

Title: Method and system for treating wastewater
Inventor: LANSDELL MARK
IPC: C02F3/30
Filed: 1992-02-14
Granted: 1998-04-28
Abstract: Conventional biological processes for treating wastewater include the so-called activated sludge process which is continuous and the sequencing batch reactor (SBR) activated sludge process.  The first process requires the use of dedicated, relatively expensive external clarifiers, and the second process is inefficient in terms of treatment volume.  A modified sequencing batch reactor process and system enable the efficient, continuous treatment of wastewater, combining the advantages of the SBR and activated sludge processes.  Wastewater is treated in three contiguous treatment sections, each of which includes a plurality of contiguous cells.  In a first series of operations, the flow direction is from the first to the third sections, and in a second series of operations the flow is reversed.  In each series of operations, the first step is to aerobically treat the wastewater, and then allow the sludge to settle before discharging the treated wastewater from the system.  The settling steps of the process include continuous flow through settling in one section, and batch quiescent pre-settling while aerobic treatment and flowing settling are occurring in other  sections of the system.
